Description: The penetrating partner sits in a chair and the receiving partner straddles the lap facing them, feet on the floor, driving a forward and back rocking against the chair back. The chair is load bearing: it takes the rear partner's weight so all of the receiving partner's effort goes into the motion.

Variations: Feet on the floor or hooked over the chair arms, hands on the shoulders or on the chair back behind. Leaning back changes it from a rock to a bounce.

On camera: Furniture gives the frame structure and the standing height puts the action at natural camera level, which is why chair positions are a production staple.

AI design considerations: A seated figure in a chair with a straddling figure above, feet reaching the floor. The chair has to be drawn, and the receiving partner's feet must actually reach, or the weight has nowhere to go.

Image to video (Ride (grind))

upper figure stays seated and moves forward and back, no vertical travel, camera is locked on a tripod and does not move.

Motion only. The still you condition on must already carry the position, wardrobe and scene: restating them causes drift.

Expected figure count: 2. Global pose conditioning does not make a diffusion model count bodies. Count figures and limbs at full size before judging quality, because thumbnails hide the failure. The tag upright_straddle is broader than this position: upright_straddle covers any face-to-face straddle of a partner who sits upright, whether on the floor as in the catalog's lotus entry or on a chair as in its face-off entry. It does not record the chair as the load-bearing seat, the receiver's feet planted on the floor, or the forward and back rocking against the chair back that names this entry, so it cannot separate this record from face-off.
